Well, I have nothing to share as far as actual material, but that's fine since the band is set to release their new album In Rainbows next week on October 10th (!!!) via this site that they posted yesterday. Basically you can name your own price for buying the digital download version of the album, but if you want the actual physical disc, a bonus disc, a copy of the album on vinyl with bonus tracks, and the accompanying hardcover book you'll have to shell out £40 (about $82 US) for the "discbox" that will be released December 3rd.
Since the band is not signed to any label and seem to have little interest in starting their own, this will probably be the only way to get the album. Be warned about their pre-order site though: it's a pain to use. Not terribly user-friendly, but if you're a fan and just want the dang album it might be worth the hassle.
